Centimeter (abbreviation: cm): is a unit of length in the SI metric system, equal to one hundredth of a metre, centi being the prefix for a factor of 1/100. The centimetre was the base unit of length in the now deprecated centimetre–gram–second (CGS) system of units.
Kilometer (abbreviation: km): is a unit of length in the SI metric system, equal to one thousand metres (kilo- being the prefix for 1000). It is now the measurement unit used officially for expressing distances between geographical places on land in most of the world countries.
How to Convert Centimeters to Kilometers
Example: How many kilometers are equivalent to 23.78 centimeters?
As;
1 centimeters = 1.0E-5 kilometers
23.78 centimeters = Y kilometers
Assuming Y is the answer, and by criss-cross principle;
Y equals 23.78 times 1.0E-5 over 1
(i.e.) Y = 23.78 * 1.0E-5 / 1 = 0.0002378 kilometers
Answer is: 0.0002378 kilometers are equivalent to 23.78 centimeters.
